App'lica'tionfled'February 5, 1916. SerialNo." 76,238:

To allwkom'it mag concern: Be it known that I, FnnnnmcK J. Osms, a citizen of the United States, and resident of Racine, in the county of Racine and State of Wisconsin, have invented new and useful Improvements in Machine-Motors, of which the following is a description, reference' being had to the accompanying drawings, which are a part of this specification.

This invention relates'to improvements in machine motors more particularly' adapted for actuating sewing or other light" machines. 4

It is one of the objects of the'present invention to may be easlly mounted upon the arm of a sewing or other light machine and which whennot in use may be swung to an out-ofthe-way position beneath the arm of the machine in order to occupy the minimum amount of space when not in use and to permit the closing of the top or arm of the machine intothetable top without removing the motor when said motor is used with a machine of the drop head or foldable type.

A furtherobject of the invention is to prcvid'e a machine" motor which may be swung from one position to another with" a minimum; effort and which motor will be automatically retained ineither position.

A. further object of the invention is to provide a machine motor in which the" driving wheel of the motor is yieldingly held in engagement with the driven" wheel of-the' machine. g k v A further object of the invention is to provide a' machine motor more particularly adapted for attachment to a Singer sewing machine and which motor may be so attached without in any mannerw rring-drill: ing or cutting attaching openings in the sewing machine and whi h will permit the closing of the armor head into the table top without remo in the mama v r A further object of theinvention is to provide an electric motor which isof simple construction",- is strong and durable and is well 7 adapted for the purpose described.

With the above"v and other objects inview thei'nvention' consists of the improved machine motor and its parts and combinations as set forth in the claims, and all 'equivalents thereof.

rovide a machine motor which chine arm and the motorconnected thereto;

and-

Fig, 4 is a horizontal sectional view taken on line 4l of Fig. 3.

Referring to the drawings the numeral 8 indicates in part the arm of a sewing machine of ordinary construction to which the improved electric motor 9 is attached. The arm comprises the upright column or standard 10 and the horizontally extending portion 1 1 projecting from: the upright and through which the horizontal driving shaft 12 extends and has its bearing. A hand or driven wheel 13mounted on the rear end of the shaft 12 is yieldingly engaged and driven by a grooved driving pulley 14 mounted on the armature shaft 15 of the motor 9. The wheel engaging portion of the pulley is preferably formed of cork or other like material to provide the necessary frictional engagement between the pulley and the hand wheel. I

' Sewingma'chine arms of the Singer type are usually providedwith athreadedopening 16 in the' rea-r portion of the column 10 to permit the connection thereto of hand attachments for some trade. Advantage is takenof this threaded opening and it is utilized in connection with a screw 17 for attaching a curved bracket arm 18 thereto.

This bracket arm is curved to extend around a part of the upright column 10 and at its rear end is provided with an opening 19jthrough which the screw 17 extends, and at its forward end isprovided with a hearing opening 20 which extends upwardly, forwardly and inwardly at an angle to receive the downwardly extending pivot pin 21 of the motor 9. The pin 21 is connected to and offset from the motor by an offset arm 22 which is rigidly mounted on the casing 23 of the motor. The pivot pin 21 is so inclined with relation to the sewing machine .arm that when the motor is 1n actuating position the motor will be 1n upr ght position with its armature'extending 1n a line parallel to the horlzontal machine shaft 12 and on one side thereof,'and when the motor is swung to an inoperative position it will be positioned directly beneath the horizontal portion of the sewing machine arm and at an angle thereto.

In order to hold the motor in both positions a coiled spring 24 is connected at one endto one of the motor casing bolts 25 and at its other end is connected to an eyed projection 26 of the curved bracket arm 18. It will be noted that the motor in swing ng from one position to the other Wlll sw ng the outer end portion of the coiled spring from one side of the ivot pin 21 to the other thus causing the spring to exert its tension to hold the motor in either position. The slight inward inclination of the pivotal connection also provides for the weight of the motor exerting a tendency t maintain the motor in either position.

It will also be noted that the spring extends at a downward angle from the motor to the curved bracket to hold the two portions of the pivotal connection together.

When the motor is in actuating position the coiled spring will hold the motor driving pulley yieldingly in engagement with the hand or driven -wheel of the sewing machine and when it is desired not to have the sewing machine actuated by the motor, the motor may be swung to a position beneath the sewing machine arm where it will be out of the Way and it will occupy space not ordinarily utilized.

Current is supplied to the motor by wires 27 and the speed of rotation of the motor is controlled in anymanner desired.

From the foregoing description it will be seen that the machine motor is of very simple construction and may be easily attached to a sewing machine.
